Does anyone really believe what happened at the Reichenbach Falls? A great many accounts have been written but it seems to me that all of them have left something to be desired — which is to say, the truth.

It is 1891, and Sherlock Holmes and Professor Moriarty have just had their confrontation at the side of the Reichenbach Falls. The novel opens with a brief account of a murder in London before joining our narrator, who identifies himself as Pinkerton agent Frederick Chase, at the Meiringen police station. He tells us that he is on the trail of an American crime boss named Clarence Devereux. It seems that Devereux was planning to join forces with Moriarty. Chase was trying to prevent such a merger, and now he wants to take the opportunity to put a stop to Devereux’s activities in London for good. He teams up with Scotland Yard detective Athelney Jones – a name recognizable to readers of The Sign of Four. Jones and Chase go back to London, where they follow a grisly trail to unmask Devereaux. Jones attempts to fill the gap left by the loss of Sherlock Holmes, with Chase as his Watson. But Chase has his own agenda, and things are much more complicated than they appear.

This is another book that I’ve had on my shelves for a long, long time. It was a selection from the Mysterious Bookshop’s Historical & Traditional Crime Club. I think it was the first book I received, actually. At the time, I hadn’t yet read House of Silk, so I put this book on the shelf. I eventually that one from the library, but found it rather darker than I was expecting, and I wasn’t in a hurry to drop back into that particular vision of Victorian London.

As it happens, the subject matter in this book was easier for me to handle, but there’s a twist in the book that I found more irritating than thrilling. Plus, queer coding a villain (along with our narrator letting us know that he “had seen his type many times before and felt revolted”) feels like a cheap shot.
